This document outlines a process for teachers to analyze student performance data, reflect on factors that influenced outcomes, and take action to improve results. Teachers are prompted to examine changes in proficiency and growth rates, consider what drove those changes, and identify strategies to enhance learning gains. They are also asked to evaluate how well formative and interim assessments predicted end-of-year outcomes and determine ways to better link assessment data to student needs. The overall message is that an effective cycle of looking at data, thinking critically, and acting on insights can help teachers successfully guide students.
